How To Choose The Best Air impact Wrench? – Buying Guide

If you are looking for the impact wrench for a specific purpose, it doesn’t make sense to look for all the market models. You should never look for the wrench just because it has advanced features and is costly. If any product is costly, then it doesn’t mean that it will display powerful results. To make the whole task so much simple and easy for you, here we have few basic tips which you should follow during shopping:

  • Size Of Impact Wrenches

The first thing you should be careful about is the size of the impact wrench. Impact wrenches are available in two standard sizes, which are ½ inch version, and the second is the ¾ inch one. Both of them have different requirements, and thus you should look for one option which is compatible with your requirements.

Talking about 12-inch, you should look for a device that is capable of delivering almost 5 CFM at 90 PSI. Whereas for the ¾ inch wrenches, the pressure should be 7 CFM at the 90 PSI! If any machine that has been fitted for the former wrench will never work suitably for the latter one. Choosing any machine which is available in1/2 inch version is completely pointless and yet expensive.

  • Portable Nature

This has been another important factor which you should consider when it comes to choosing the best one. All those devices which are based on the 60-gallon tank or even above are pretty much heavy. Still, if you are choosing it, then mobility will be the biggest concern. Some of the models are also available with the wheels to move smoothly.

So it is always needed to look for a wrench that is portable and easy to carry around. Those smaller devices based on the tank capacity of almost 20 gallons or even lesser are easily portable, and even weigh less.

  • Oil-free Or Lubricated?

Some of the units will function without the oil, and some of them will require the need of oil lubrication. All such oil-free models are known to be best for the environment and will also save so much of your effort and time. Additionally, lubricated machines are also considered to be so much power, and they will last longer. Plus, their parts will also wear down very slowly on frequent use. Both have their pros and cons, so you should choose the one based on your suitability level.

  • Noise Levels

This is one such aspect that many of us ignore, but when it comes to the long-run, the importance of noise levels should never be ignored. There are different options available for the models which do not make a single noise while working. They are not just beneficial but even stop you from disturbing the people around you.
